Launchpad integration

It would be great if there was some sort of Launchpad integration that could be introduced with Synaptic or mintInstall. I often have to go hunting down PPAs to get programs and applications that don't make it to the default repositories, yet are still useful in their own ways. In particular, I often go to Launchpad to hunt down updated versions of common applications (take Firefox and Thunderbird for example). Even something as simple as being able to search for Launchpad PPAs from Synaptic's GUI would be helpful for a relative newbie trying to look for updated/additional software.
